I shall shortly be eighty-eight. High time to be giving serious thought to the direction my life should be taking. In an upper-crust retirement home, Geoffrey Wythenshaw sits down to write his memoir. But he faces constant interruption from his fellow residents, attending staff and an invasion of downmarket pensioners from the Cairngorms. Some of them seek his wisdom, others only distraction. Examining with heart and humour what it means to grow old, N. F. Simpson's "If So, Then Yes" premiered at the Jermyn Street Theatre, London, in September 2010, in a production by Presence Theatre.
